Answer:
No solutions
Step-by-step explanation:
3x+4y=-4
15x+20y=-22
——————————
-5(3x+4y)=-5(-4) multiply 1st equation by -5 so you can eliminate the variables
-15x-20y=20. Modified 1st equation
15x+20y=-22. 2nd equation
0+0=-2. Added two equations together
since 0 does not equal -2, there is no solution.
Answer:
14 rides
Step-by-step explanation:
16 = 0.79x + 4.5
11.5 = 0.79x
x = 14.55 or 14
rounding down because it can't go over $16.
0.79(14) + 4.5 = $15.56
Answer:

r=all the y values
Step-by-step explanation:
Hello!
Let's multiply each thing here.
4(4)=16
3(5)=15
15=16=31
50-31=29
